Anon 1: Yes, you’re right. Thanks for catching my silly mistake. Yikes. I typed this on the bus and didn’t proof-read it. 

Anon 2: That’s also true. I was just giving a few examples. If you search the diary tag/ New York tag on Bamboo Thicket, Himaruya talks a lot about his time spent in New York, which included rooming with people from different nationalities. It provides a lot of perspective on how some of his experiences were incorporated into the manga.
